Happy Fourth of July!
If you're drinking beer, add salt to the ice water bath. From Mythbusters, or rather an bloggish sort of fan site about the show:
Experiment 1: Ice vs. Ice + water vs. Ice + water + salt vs. fridge vs. freezer
Initial measurements:
* Ice
* Ice + water: 33 degrees
* Ice + water + salt (salt melts ice and lowers the freezing point): 24 degrees
Results (after 5 minutes):
* ice: 57 degrees
* ice water: 44 degrees
* salt water: 35.9 degrees
* freezer: 55 degrees
* fridge: 60 degrees
Final results [time needed to cool to an unspecified cold temperature]:
* Ice + water + salt: 5 minutes
* Ice + water: 15 minutes
* Freezer: 25 minutes
* Ice: 30 minutes
* Fridge: 40+ minutes
Incidentally, a fire extinguisher will also cool beer down to a frosty 37 degrees in three minutes flat.
